Analysis of composite bonded/bolted joints used in repairing

The performance of composite repairing using single lapped joints is sensit ive to factors such as ply stacking sequence of laminate, bonding surface p reparation, anisotropic nature of adherend, as well as bearing and load tra nsfer from one adherend to the other. This research is focused to investigate the stress distributions in laminat ed composite joints with multiple pin loads using finite element analysis. The structural response of various configurations of single lap joints, nam ely bonded, bolted and bonded-bolted joints, are analyzed by three-dimensio nal finite element method. A comparison of the results obtained using finite element analysis is condu cted with experimental results and the results are validated. Parametric st udy is conducted to investigate the effect of stress distribution and load transfer due to ply stacking sequence of laminate.
